C# :: Reading Map Data From Streamreader

So what I'm trying to do is read map data from streamreader, which is very new for me, I already managed to generate maps using code inside the IDE but im very confused on how I would read it from a file. What I'm trying to say is that I understand how to create a map from the map data, but I dont know how to put that map data into text files which would make my job much easier.

My Game1:

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;

[Code] .....

Tl;dr basically, how would I go about using streamreader to read the map, and include the required commas and curly braces. I have already used Streamreader for other things and failed miserably.
